Title: Drive system for ac motor
Inventor: FUJIOKA YOSHIMOTO
IPC: H02P21/00
Filed: 1982-07-14
Abstract: PURPOSE:To control to smoothly decelerate an AC motor without disorder of torque by stopping energization at a specific angle of an electric angle when the control of the motor is shifted from power drive motor to a regenerative motor. CONSTITUTION:A polarity discriminator 201 outputs a polarity change signal PCS to a microcomputer 112 and a monitor 202 when the polarity of a speed deviation signal epsilonr varies. The monitor 202 counts a resulting pulse Pt from the generating time of a signal PCS, and when the resultant pulses of N/2 pieces are generated, a timeover signal TOS is outputted to the microcomputer 112. The microcomputer 112 inhibits the sinusoidal output by the signal PCS, and outputs a counting direction inverting signal CPS to a counter 111. When a signal TOS representing that 1/2 period is elapsed is generated, the microcomputer 112 again outputs sinusoidal wave of 2-phase on the basis of the counter value of the counter 111. In this manner, when the AC motor is shifted in control from the power drive motor to the regenerative mode, it is stopped energization at 180 deg. of an electric angle, and can be smoothly controlled in deceleration.

Title: Image processor
Inventor: NAKADA TOMOYUKI
IPC: G09G5/00
Filed: 1992-04-17
Abstract: PURPOSE:To provide an excellent image processor which can show the smooth halftone gradation with suppression of the conspicuous level difference of gradations by using an error scattering method when the image information is binarized as the multilevel data. CONSTITUTION:An input image reading sensor 11 reads the image information on the picture elements having the gradation and produces the analog signals accordant with the gradation of picture elements. An A/D converting part 12 converts the analog signals of the sensor 11 into the multilevel data. A gradation converting part 13 transmits the remainder produced when the multilevel data on an optional picture element is divided by the prescribed numerical value as an error component. Then an error scattering part 14 scatters the error component to an optional peripheral picture element. An image scanner device 1 contains these sensor 11 and parts 12-14 and supplies the image information undergone the error scattering processing to a display device 2.

Abstract: PROBLEM TO BE SOLVED: To enable the highly accurate measurement of amylose content in polished rice by performing partial least square regression analysis on the basis of an actual content value obtained in the process of the chemical measurement of a reference value of amylose content and absorbance measured in the process of the near-infrared spectrometry of an amylose content value and obtaining a specific equation predicting amylose content, and performing computations. SOLUTION: Milled-rice samples are collected, and a value of amylose content to be a reference value in the case of performing regression analysis, etc., is measured from the collected polished-rice samples by a chemical analysis method. In parallel with the process of the chemical measurement of a reference value of amylose content, the polished rice is irradiated with near-infrared light to obtain the spectrum of the transmitted light and to measure absorbance at each wavelength. Next, letting the actual value of amylose content obtained by the chemical analysis method be an object variable and the absorbance by near-infrared spectrometry be a predictor variable, regression analysis is performed to obtain a conversion equation (calibration curve) with high correlation and few errors.  Then the absorbance data on the rice samples by near-infrared spectrometry is applied to the calibration curve to evaluate the predictability of amylose content.

Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To make a design efficient by previously preparing respective kinds of unit brace structures included in a prefabricated building and a list indicating D-values corresponding to these structures. SOLUTION: A list is prepared, which indicates respective kinds of unit brace structures in which a brace is provided in a square frame where an upper beam and a lower beam connect between the upper ends and between the lower ends of adjacent two columns respectively and specified D-values corresponding to respective unit brace structures. Whereas, D-value expresses a horizontal load necessary for bringing a unit horizontal displacement to the upper beam by the action on the upper beam of the unit brace structure and it can be calculated in a specified equation. When designing a prefabricated building, a stress on true brace, the center of rigidity of respective floors, a torsion, a story deformation angle, and an eccentricity are calculated by using the D-values.  The contents of the list are input in a computer to store them instead of the list or a required calculation is executed through the computer. In this way, since the D-values are not required to calculate repeatedly, a designing work is rapidly carried out.
